' CARRIAGE-DOOR.

SPECIFICATION forming part of Letters Patent No. 430,026, dated June 10, 1890.

Application filed December 19,1889. $erial No. 334,293. (No model.)

To all whom it may concern.-

Be it known that I, JOHN F. I-IURTIG, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Carriage Attachments, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

This invention relates to devices for hanging carriage-doors and for the fastening, antirattling guideway and inclosure, &c., of the windows of said doors; and the invention consists in features of novelty, hereinafter fully described, and pointed out in the claims.

Figure I is a detail side view of a carriage to which my invention is attached, and shows the sash elevated,.with part of the windowframe broken away to show the pivoted flapper and its hinged bearings. Fig. II is an enlarged detail inside perspective View of the door and body-pillar, and shows the concealed hinge and flapper attachments, the door being open. Fig. III is a like view with the door closed and the hinge concealed, and shows in full lines the flapper raised, with the anti-rattler friction-springs attached within, and in broken lines the said flapper lowered into the position in which it covers the lowered sash. Fig. IV is an enlarged detail of the flapper, and shows the pivotal attachment end thereof. Fig. V is an enlarged perspective view of the integral bracket that is secured to the door pillar and bar and ties the same, and which bracket carries the pivot-bearings of the flapper and shows its outer combined center and peripheral bearing. Fig. VI is an enlarged vertical section, and shows the boxed bracket and flapper pivotal attachment, the sash being elevated. Fig. VII is an enlarged perspective view of the face attachmentboxing-plate, through which works the concealed hinge. Fig. VIII is an enlarged perspective view of the detachable pivot attachment block, on which the perforated hook of the concealed hinge works. Fig. IX is an enlarged perspective view of the hook of the concealed hinge and its flange attachment plate, by which it is secured to the door-pillar.

Fig. X is a horizontal section taken on line X XI, Fig. XII, and shows the concealed hinge retired into its boxing, the door being closed.

Fig. XI is a like view taken on the same line, the door being open. Fig. XII is a vertical section taken on line XII XII, Fig. XI, and shows the screw-lock attachment of the pivotblock that carries the concealed hinge. Fig. XIII is an enlarged perspective View of the pivot-block, and shows the boxing in which the locking-screw engages to secure its attachment; and Fig. XIV is an enlarged perspective View of a modification of the integral boxed bracket, otherwise shown in Fig. V, and which modification shows a lateral extension of the horizontal arm of said bracket that both stiifens its attachment and in which is provided an underlying drip-catch beneath the outer bearings which catches the drip therefrom when it rains and diverts its course through a drainage-duct from the outer bearing-seat of the flapper.

Referring to the drawings, 1 represents a carriage to which my invention is attached, a detail of which is shown in Fig. I.

2 is the carriage-door, and 3 the sash of the drop-window in said door.

4 are the body-pillars of the carriage; 5, the door-pillars; 6, the casing or paneling of the door, and 7 that of the carriage-body.

8 represents the'bow-neck or hook member of the concealed hinge 9, which is secured to the door-pillar by screws 10, that pass through the screw-holes 11 in the attachment flangeplate 12 that is integral with said member of the hinge, and which screws are screw-seated in the door-pillar to attach the hinge thereto.

13 represents a detachable lock block, which carries the pivot-pin 14., that constitutes the other member of the hinge, and which pivot-pin works in the perforation 15 in the bow-neck portion of said hinge, the said pivot-carrier detachable block, when attached, being the stationary member of the hinge, and the said bow-neck portion being the movable member thereof. The said pivotpin of the hinge is preferably loose riveted within the bevel countersink of the perforation 15,so that although saidhinge-block is detachable from its locking-seat, about to be described, yet it is not individually detachable from the bow-neck movable member of said hinge, which, however, moves freely on the pivotal pin that projects from Said block, whose rivet-head moves readily in its countersink-seat. The enlarged shoulder 16 at the foot of said pivot works within the annular enlarged box-bearing 17 at the lower end of the perforate bearing 15 in the bowneck member of the hinge, and thus constitutes an enlarged shoulder to the pivot-journal or a peripheral journal-bearing beneath, that is surmounted by a center bearing above, which latter is the usual pivotal center hearing. Now it will be seen that this enlarged or peripheral journal-bearing is both much stronger than the usual center bearing, and thus more reliable, and also itis much stifferthat is, there is not the spring to it that there is to the common journal-pinwhen, as is usually the case, the door of the carriage is slammed to in closing; also, the said hearing is stronger at the base, where, under adverse leverage, it has to withstand the greatest strain. The concealed hinge is housed and works in arecessed boxing 18 in the bodypillar of the carriage on which said door is hung.

19 represents the face attachment boxingplate, which has an inner metallic boxing 2O integral therewith that inwardly proj ects from said attachment plate and is housed within the larger recessed boxing 18, in which the concealed hinge is hid and works. The said attachmentplate is secured to one of the bodypillars l of the carriage by screws 21, that pass through the screw-holes 22 in said plate and are screw-seated in said pillar. The said inner box 20, that is integral with the attachment plate 19, is provided with a buffer-plate or flange 23, against which the bow-neck or hook of the concealed hinge buffs when the carriage-door swings open. Beneath said buffer-flange plate and integral therewith is the said inner boxing proper 20, the boxchamber 24 of which (in which is housed the lock-block 13) is of an oblong shape and is surmounted by inwardly-projecting flanges 25, that partly inclose said box-chamber. The bottom 26 of said box-chamber is shaped in a brace-angle form that thickens as it approaches the face attachment plate, with which, as stated, it is integral, thus forming a strong brace hold and re-enforce attachment for the boxing.

The detachable lock-block 13, which, as previously stated, carries the pivot-pin and enlarged peripheral bearing of the concealed hinge, is so constructed as to slide within the box-chamber 245, in which it is screw-locked, as will be described, so as. to provide an attachable and detachable locking-connection for the concealed hinge. The said block has laterally-projecting lugs or side wings 27 at its base, which, when said locking-block is inserted in its locking-seat, slide in the guideway channel-grooves 28 in the box-chamber 24, which channehgrooves are formed by the inwardly-proj ectin g flanges 25 that surmount them. A lockin g recess-chamber 29 is formed in the under side of the detachable lockingblock, as shown in the inverted block in Fig.

hook of the other member of the hinge.

XIII, and in the vertical section that passes through said block in Fig. XII. The locking set-screw 30 is screw-seated in the perforate screw 31, that passes through the attaclnnent face-plate l9 and through the thick anglebottom 26 of the box-chamber 24:, that houses the locking-block, the head of said locking-screw, when operative, being housed out of interference with the working of the hinge or door in the bevel recess 32 at the entrance of said perforate screw, which recess flares outward at the face of said attachment plate 19. The point of said screw enters within the locking-chamber 29 when it is screwed home and screw-locks the concealed hinge in its operative seat. An integral pendent flange 33 at the outer end of the detachable lockblock 13 (when said block is slid home) is seated in the countersink or recess 34, beneath the entrance to the box-chamber that incloses said lock-block, and thus gages the required depth of insertion of said block and the consequent working position of the concealed hinge. Now it will be seen that when it is for any Cause desired to remove the carriage-door it is not taken, as is usual, from its hinges, but said door is opened, as shown in Figs. II, XI, and XII, and the locking set-screw is then retired sulliciently to vacate the locking recesschamber 29, when the door with its concealed hinge or hinges intact can be easily removed from the body of the carriage. The two members of the hinge-joint still retain their relative position to each other, as the outer end of the pivotrpin is loose-riveted within the bevel-countersink at the upper end of the perforation 15 in the bow-neck or It will also be seen that the locking set-screw, when retired from its locking position, is not withdrawn from its screw-seat, but is there retained for future service, so that there is no danger of its being mislaid or lost. Now it will be seen that not only is there in this part of my invention a ready means for looking and unlocking the attachment of the carriage-doors and their hinges, but also the enlarged peripheral bearings at the base of the pivotal connection of said hinges is an ellicicnt safeguard from the straining of the hinge from the frequent hanging of the carriage-doors; also, the concealed housing of the hinges not only conduees to an improved appearance of the carriage, but it also protects the hinges from the tarnishing and corrosive elfects of rain and dampness and provides a freer swing to the hinge-bearings.

35 represents the integral boxed bracket cast in one piece, and which is secured to the pillar and bar of the carriage-door that is hung by the above-described concealed hinge or hinges. The said integral bracket is of a combined vertical and horizontal conformation, and its respective integral parts are sooured to said pillar and bar of said carriagedoor (and thus form a re-enforce tie-coupling of the same) by the screws 36, that respectively pass through perforations 37 in the boxed vertical arm 38 of said bracket, and areseated in the door-pillar 5, and like perforations alike numbered in the horizontal arm 39 of said bracket, and are seated in the horizontal door-bar 40. The angle flange sides 41, that with the perforated attachment plate of the vertical arm gives it its boxed construction, constitutes it a guideway 42 for the direction of the window-sash 3 of the door as said sash, with its incased window43, is elevated out of the housing 44 within the door or retired within said housing. The integral boxed bracket is inlaid and embedded incut-away recesses 45 in the wooden pillar 5 and bar of the carriage-door that conform to the under and outer shape of said bracket. v

46 represents a bearing-plate, which is 0011- stituted from a surmounting extension of one of the angle-flanges 41 of the boxed vertical arm 38 of the bracket 35. The said bearingplate is an integral part of said bracket, and

near its center is provided with aperforate bearing 47, in which the journal-pin 48 of the flapper 49 has its bearings. The said journal-pin is integral with and project-s outwardly from the inner curvilinear foot-base 50, which is an enlarged extension of the inner side flange 51 of the flapper and constitutes a pivot journal-bearer on that side of said flapper.

52 represents an enlarged peripheral journal on the opposite side of the bracket 35 to that occupied by the bearer-plate 46, and which peripheral journal is also integral with said bracket, and 53 is a center pivot-journal that projects outward from the middle of said peripheral journal, which latter (the peripheral journal) works within the peripheral boxbearing 54 in the outer curvilinear foot-base of the side flange 51 of the outer side of said flapper, which foot-base and flange are alike numbered with the corresponding parts on the inner side, and the former (the center bearing-journal) works within the perforate center bearing 55 in the foot-base of the outer flange of said flapper. A surmounting extension of the long flange 41 of the vertical boxing of the bracket 35 constitutes the dividing-partition 56, over which the window-sash is lifted when elevated, and has its drop-seat on the horizontal bracket-arms 39 to hold it in its elevated posit-i011 and prevent its retirement within the housing 44 in the door. The fourfold functions of the pivoted flanged flappers, which are placed in duplicate, their bracket-bearers being also in duplicate on each side of the door-window, are, first, when elevated or lowered in its vertical position as a guideway to direct the sash of said window while elevating and lowering; second, as a retainer to hold the sash captive within its allotted bounds; third, by the aid of the friction-springs 57, that are housed in the guideways provided by said flapper and work inwardly from the flanges 51, to which they are secured by brazing or by any other suitable means, being arranged so as to'exert a springpressure against the sash, the flapper constitutin g an anti-rattler device on each side the sash, and, fourth, when the sash is lowered to its housed position within the door the flappers on each side are folded down, turning on their pivot j ournal-bearings toward each other, their loose ends registering with each other in the middle of the door and neatly covering and closing in the housed sash, the frictionsprings 57 again engaging with the sash, so as to hold it as an anti-rattler in its lowered as well as in its elevated position.

58 represents a drain duct that passes through the horizontal arm 39 of the bracket 35, its mouth receiving the drip (when the carriage is out in the rain) from the outer bearings of the flapper, which drip is caught by the laterally-extending flanged edge 59, from which it runs through said drain-duct and is delivered through the open housing in which the sash is lowered. There is not sufficient drip to cause inconvenience in said discharge; but when confined in the journalbearings it causes considerable injury by the corrosion of the brass, and should frosty weather set in inconvenience is experienced by frost-locking of the bearings, which this drain-duct obviates.

Among the most important features of the invention are, first, the concealed hinge having its journal-bearing on a detachable block to which it is pivotally secured; second, the said block having a sliding attachment in a locking-box within one of the body-pillars of the carriage; third, the single locking-screw and its means of insertion to eifect. the lock of said detachable block by which the attachment of the concealed hinge is locked; fourth, the combined peripheral and center journals integral with the detachable lock-block of said concealed hinge; fifth, the combined box and center bearings in the perforate member of said concealed hinge, that greatly adds to the strength and stiffness of the hinge attachment; sixth, the integral combined bracketbearer and tie, which by its vertical boxed arm and horizontal arm, (cast together,) the former secured to the door-pillar and the latter to the transverse bar of the door, thus reenforces their frame-coupling tie together; seventh, the pivoted flapper with its four several functions previously described; eighth, the combined peripheral and central journals on which said flapper pivots; ninth, the combined box peripheral and center bearings of the flapper, and, tenth, the friction anti-rattler springs within the flange-boxing of said flapper, that possess two functions in connection with the door-sash, constituting both an anti-rattler and friction-brake to ease the fall of the window in its descent.

All the above-named parts are preferably made of brass, but maybe made of any other suitable material.

I claim as my invention-- 1. In a carriage attachment, the combination of the bow-neck member of the concealed hinge, the said member provided with the combined peripheral box and center pivotbearing, the detachable block, and the combined peripheral and center pivot-journal carried by said block that engages in the combined peripheral and center bearing of said bow-neck of the hinge, substantially as described, and for the purpose set forth. 2.
